Specification of Letters Patent. 1

Patented Dec. 25, 1906,

Application filed July 6,1906. Serial No. 324,919-

To (til whom it may concern:

Be it known that I, FRANK E. SEELEY, a citizen of the United States of America, residing in the city of Bridgeport, of Fairiield and State of Connecticut, have invented certain new and useful Improvements in lncandescent-Lamp Sockets, of which the following is a specification.

My invention relates to incandescentlamp sockets and the like, and particular] to the means of fastening together the she l and the cap, the object of my invention being to provide a ready and secure means whereby the parts may be attached or loosed.

In the accompanying drawings, Figure 1 is a side View of the cap and shell detached. Fig. 2 is a perspective view of the same with the cap inverted. Fig. 3 is an interior View of the ca Fig. 4 is a cross-section on the line-4 4, ig. 3. Fig. 5 is a cross-section on the same line, but showing the cap tilted back preparatory to removal. Fig.- 6 is an enlarged cross-section on the line '6 6, Fig. 4; and \Fig. 7 is a side elevation of a modification of the ca Referring to the drawings, the cap A and the shell C are made of any suitable material, but )referably of the usual drawn sheet metal. The cap is'provided with the usual circumferential flange B, within which the shell fits when the parts are attached.

My fastening device is as follows:

A spring-tongue 1 is attached to the caprim by rivets or otherwise, as shown in Fig. l, or is cut from the rim, as shown in Fig. 7. This tongue is provided on its inner face with a projection 2, forming a beveled catch, which may be convenient y stamped. from the tongue itself.

At points on the rim of the cap approxirovided acing in side approxinmlely parallel to the axis of the socket and one side in a pla'!" approximately at right. angles to said axis. 'lhcse projections may be conveniently made by stamping the same from the inner face of the rim of the cap, as shown in the drawings.

in the county ceive the When the cap is fitted upon the shell, the

In the shell at appropriate points are provided holes 5, of suitable shape, to receive the projections 4 on the rim and a hole 3 to reprojection 2 on the tongue.

projections carried by the ca enter the cor responding holes in the she I, and the cap cannot thereafter be either rotated or removed except as hereinafter ex lained. The rotation of the cap is prevented by the oppo- 6c sition of the face of one or other of the holes 5 to the face a of one or the other of the angled rojections 4, whichever way the cap may )0 turned, while the faces 6 of these projections 4 and 2 prevent the shell from being removed endwise from the cap. The shell may be removed, however, if the tongue 1, carrying the projection 2, be first sprung away from the shell by means ofthe finger or any instrument inserted under the flared end 6 of the tongue, and the projection 2 thus lifted free of the hole 3. The ca) may be then tilted back until the faces of t 1e angled projections 4 are clear of the holes 5. The cap is thereby entirely freed and may be removed at wil I claim as my invention 1. .ln incandescent-lam sockets,the combination of a shell with t ecap, and means for attaching the shell and cap together, con sisting of a spring-tongue carrying a beveled catch borne by one part and faced angled projections borne by one part, the other part iaving holes to receive the angled projections and the beveled catch.

2. An incandescent-lamp socket, having a cap provided with oppositely-faced angled projections on the inner face of the" firm, a tongue provided on its inner face with a beveled catch, and a shell provided with holes suitably placed to receive the angled projections and the beveled catch when the cap and shell are fitted together.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
